. ANIMAL TRAP.

Application.filed november 23, 1927. Serial no. 235,308.

This invention 7 relates to new and useful:

, improvements in traps, and particularly to animal traps. 1 1 One object of the invention isto provide a trap wherein the animal resets the trap, after having been trapped, so that a subsequent animal may freely enter the trap. 1 Another object is to so arrange a barrier, and bait, thatthe animal will spring the trappupon attempting to reach ,thegbait, thereby forcing the animal to proceed'past tion.

Another object is to provide a barrier Figure 2 is a vertical longitudinal section- I a1 view on the line 22'of Figure 1.

Figure 3 is a similar sectional view showing the trap sprung. Referring particularly to the accompany ing drawing, 10 represents a cage orbox,

. which is provided with a longitudinal partition' 11, separating the box into two com-v partments 12 and 13, the'formerofwhlch serves as the entry, through which the animal passes, after having entered through the 1 storage space for trapped animals, until such. time as they may be removed for destruction.

opening 14, in one end wall of the box, while the other compartments serves as a 'Fivotally'supported above. the opening? 14:,

and arranged to vswing downwardly into closing relation thereto, is a door 15, formed .ofsheet metal, and doubled on itself, with the portions thereof slightly sepa- I rated, for the reception therebetween of the bight portion 16, of the wire yoke 17 This yoke has the ends of its arms pivotallysupported on a transverse shaft 18, which ex-.

i tends through the side wall of the box, and said partition, djacent the bottom of the box. Extending at an acute anglefrom the pivotalportion of each of the arms of 1.we1ght of the door 15 'causetl iesame to the yoke 17, inthe plane' of arm, is the" arm 19, which is" terminally formed with an eye 20,.in which i-sreceived,

an end of a wire link 21'. A yoke122, having each of'its arms in the form of a bell crank lever 23, is pivotally supported on transverse shaft 24-, which isdisposed through-the said side wall of the box, and'the said parti:

tion 11, this shaft,'howeve r, being arranged i adjacent-"the upper portions of said walls, and at a suitable distance inwardly of the entrance opening 14. It will be noted that I one arm of each of the bell crank levers23 extends downwardly,and that the adjacent or other end of a link 21is pivotally connectedtherewith. It will further be noted that t-here'remains'a small portion'of the; end of f e'a'ch'of'the said arms or the bell crank levers,

below. the connection of the links. Pivotally mounted adjacent the floor offthe compartmenjt '12,'is atiltable platform 25, the forward, or inner endof which is arranged to engage with 'the before-mentionediproj ectin g portions of the arms of .the bell cranks", whereby, when the said platform is in ele vated,'or set position, its forward edge re- 24, and has its lower end in position to lie against the forward edgeof the platform, whereby to prevent movement of the door animal to pass over the platform, and enter the compartment 13, throughthe' passageway 7 27, formed between the inner end of the tains the yoke 22 against pivotal movement, 1 until released by .the depression of the plat-f form .under the weight of an animal- A. door 26, formed preferably of wire' screen, is pivotally suspended on the said shaft partition 11, and the adjacent end of the described,-the door 15 is in elevated posibox. When the parts are in the position thus enter through the opening l l, as. will be evident, A bait receptacle28 is formed on the inner face of the screen door 26,"which the animal attempts to reach by passing over the platform '25. Immediately upon the such platform will tilt wherebyto move the forward endofthe platform below the ends.

j animal placinghis weight on theplatform,

' swing into closing position inwardly of the opening14,-, and atthe same time rock the yoke17 so that itsbi'ght portion slides down to the lower edge of such'door, thereby preventing any attempt to swingfihevdoor inwardly from the outside. The animal is thus trapped between the door and the screen door 26, with the result that esca e' through the vopening llis prevented. T e

, animal then attempts to, reaoh'the' bait, by steppingj'o'n and depressing r the platform,- With theresult that he mayswingfthe door: 26"l11WflI'Clly'and el'lliel'f tll' inner end otthe chamber, or compartment. 12-. When the door 26 swings back into its normalpost i ti n,'it-rests against the forward edge 'oi'the 1 platform-, thereby preventing'the"animal moving the door inan attempt to get back into 'tl e'compartme'ntl2, The only course 'left for the animal is topass'into the compartment 13. On oneend wall ofthe com removed for; destruction. 7

an animal enters the trap, and passes beyond the 'door- 26, thetrap is reset for the next" animal, With the result that'the trap is alpartment13' there 'is' formed an opening 29, closed by a "removably arrangedj slid'ab'l'e door 30,- through which the" animals may be Thus, each time vvays ready for the entrance o1an'animal Beneath the platform there is disposed a spring 31 which yieldably maintains the plat form in elevated position, 01; stopping eng-agement with the door 26.

What is claimed is? '1. Anammal trap including an enclosure havlng anentrance openlng, a door controlling said opening, a swinging barrier a r- J rangedinwardly of the door, a trip adjacent the barrier and normally holding the ,latters-from movement in one direction; a yoke mounted in the enclosure 'and'movably connected with thedoor' for opening and closing the same, a second yoke mounted in the enclosure, connections? between i the vyokesrthe bightof the'second, yoke arranged. in thepath of the barrier whereby to" be engaged ancl moved therebywhen an animal moves'saidbarrier to restore the said door to open position;

2. An "animal trap' including an enclosure having an entrance opening,a doorinovable toward'and away from the opening,v i swinging barrier mounted sinwardlyfof the door, a trip operable by Jan' animal normally-holdwill be closed, and upon"movement 'of 'the barrier by an animal the door will be-opened." i V In testimony whereof, I' afiix my signature.
